Emperor Yiguang of Han Zhao

Emperor Yiguang of Han Zhao (died 329), born Liu Xi, was the final emperor of Han Zhao, succeeding Emperor Guangchu of Han Zhao. He was killed by the Later Zhao dynasty at Tianshui, destroying Han Zhao; the Xiongnu nobility was massacred by the Later Zhao forces.

Biography
Liu Xi was the son of Emperor Guangchu of Han Zhao and Yang Xianrong, and he was made crown prince by his father upon his seizure of power in 318. Liu Xi and his older brother Liu Yisun often argued about the succession, as Liu Yisun was the older brother. Liu Xi had to yield to his older brother at ceremonies, but their relations remained cordial, and they never had to go to war. In 329, his father was captured and executed by the Later Zhao, leaving Liu Xi as the uncrowned emperor of Han Zhao. Liu Xi was captured at Tianshui by general Shi Hu later that year, and he was put to death, ending the Han Zhao dynasty.
